CULTIVATOR. ATTACHMENT.

Application filed October 20,1915. Serial No. 56,874.

To all whom it may concern:

Be it known that I, JOEL R. KELLEY, a citizen of the United States,- residing at Owasso, in the county of Tulsa, State of Oklahoma, have invented certain new and useful Improvements in Cultivator Attachments; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in Cultivators, and particularly to attachments therefor.

The principal object of the invention is to provide an attachment for a shovel cultivator whereby the cultivator can be converted into a disk cultivator.

Another object is to provide such an attachment for a shovel cultivator that the disks can be raised at one side of the machine independently of the other and their angle of cut changed.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation of a cultivator equipped with my improved disk attachment;

Fig. 2 is a top plan view;

Fig. 3 is a side elevation showing a slightly different arrangement of the disks, with the beams in raised position; Fig. 1 is a section on line 44: of Fig. 1.

In the drawings, 10 represents the beams of a cultivator which support the frames 9, said beams and the frames in turn, carrying the downwardly curved necks 8. The stems or necks 8 are shaped to receive the clamps 13, which are castings adapted to be removably and adjustably bolted around the shanks of the stems. Each clamp 13 consists of a body which is located to one side of the stem upon which it is mounted, and a pair of arms shaped to surround the stem, a bolt passed through the arms securing the latter in place. The body of the clamp is provided with a flat face which is provided with bolt sockets, so that the usual shovels 22 may be securely mounted for use on the machine.

In order to substitute disks 12 for the shovels, I have provided the brackets 21, which consist of two arms or plates which are disposed at an acute angle to one another and are formed from a continuous metal sheet or bar. One arm or plate 21 has its outer face conformed to the face of the clamp 13 and is apertured to be bolted theretoby-the bolt sockets which are ordinarily used to secure the cultivator shovels. The other arm or plate stands at an acute angle to the arm 21, as already mentioned and may therefore be adjusted with the bracket 13, to place the disks 12 at the proper angle to the line of draft. The second arm or plate is apertured to receive the bolt 15L which projects through the disk 12, the head of the bolt being countersunk into the front face of the disk, and through the hub 14:. The hub 14 is suitably bolted or riveted to the rear face of the disk 12 and its opposite end is fitted into an aperture formed in the bracket 21 and is supported therein by the bolt 14.

Suspended from the beam 25 is a chain 23, the other end of which is provided with a ring 2 1, engaged on the cross bar 19. This chain holds the arch from falling on the beams 10 when said beams are in a horizontal position, or when swung upwardly in disengaging the disks and shovels from the ground. The ends of the transverse bar 19 are received in the eyes 18 of the arms 18, and set screws 20 carried by the eyes 18 provide a means for setting the arms 18 upon the bar 19 and adjusting the former in longitudinal directions.

The links 17, the arms 18 and the bar 19 supported by the bifurcated members 15 form an arch extending from one beam to the other for preventing spreading of the beams.

If desired, a combination of shovels and disks can be provided, as clearly seen in Fig. 3. Here it will be noted that there are two sets of ground treating implements, each set including three members, the intermediate member being the shovel 22, while the outer members are the disks 12.

What is claimed is:

1. The combination with a cultivator beam, of standards depending from the beam, brackets clamped to said standards, and having flat faces provided with bolt sockets, said faces being formed to hold cultivator shovels in operative position, and brackets also formed to be bolted upon the faces of said clamps, and consisting of angularly disposed plates one of which is bolted to the faces of the clamps, and cultiacute angle, one of said plates being shaped 15 to be bolted upon said bearing face, and a cultivator disk mounted upon the opposite plate and including a tubular hub secured to the rear face of the disk and a bolt passed through the disk and hub and having a 22 fixed bearing in the last mentioned plate.

In testimony whereof, I aifix my signature, in the presence of two witnesses.

JOEL R. KELLEY.
